SPECIFICATION forming part of Letters Patent No. 721,031, dated February 1'7, 1903.

Application filed October 28., 1902.

To and whom, it may concern.-

Be it known that LHENRI EDELINE,builder, a citizen of the Republic of France,residing at 33 Rue du Repos,Paris,France,have invented a certain new and useful Storage-Brake for Vehicles, of which the following is a full,-clear, and exact description, and for which I have applied for Letters Patent in France, dated July 9, 1902; in Germany, dated July 25, 1902; in Russia, dated July 31, 1902; in Hungary, dated August 22, 1902, and in Austria, dated August 25, 1902.

This invention relates to a storage-brake applicable to vehicles of all kinds, especially to vehicles drawn by animal power, this brake restoring at the restarting the energy stored up during stopping, and thus avoiding in the case of the application to horse-drawn vehicles an excessive strain on the horse or the necessity for the addition of a second horse. In the drawings annexed, which represent a tilt-cart furnished with the improved apparatus, Figure l is an elevation of the cart in its normal working condition. Fig.2 is a plan showing the working parts under the floor of the cart. Fig. 3 is a front view. Fig. etis an elevation from the side opposite to that shown Figs. 5 to 11 are detail views. The apparatus comprises, essentially, a group of springs the winding up of which constitutes the braking force, the energy given out for braking being thus stored up by these springs instead of being lost in rubbing against the shoes, skids, &c., and capable of beingexerted at any moment upon the wheels of the vehicle. i

The outer ends of the storage-springs A are secured on the cover or casing and the other ends (that is, the centers) on a shaft (1, arranged across the front of the cart, the whole being inclosed by the cover or casing a, which constitutes a cylinder turning around the shaft and mounted on a frame a having nit-ches a which carry and retain the shaft a. At one extremity of the cover is fixed a sprocket-wheel 0t and at the other end a sprocketwheel (1?, which I term spring sprockets, in contradistinction to the sprockets, as hereinafter described, connected one with the driving wheel and one with the winding-wheel. To prevent the unwinding of the spring, I also provide, so as to turn Serial No. 129,119. (No model.)

On the frame of the vehicle on the side of the wheel B is a pivot D, on which is pivoted a lever 01 61, Figs. (Sand 7., The lower arm of this lever carries a spindle E, on which are secured a chain or sprocket Wheel 6 and a toothed pinion 6', arranged in the plane of the toothed crown b. Chains F F connect the pinion a to the chain-wheel e and the pinion a to the chain-wheel O.

To the arm '01 of the lever d d is attached a rod G, joined to a disk H, keyed to a crankshaft h, crossing the vehicle and pivoted in the bearings h. V This disk H carries a roller crank-pin h on which is engaged one end 'i of the rocking bar I, pivoted at 1 and which is jointed at the extremity of its arm 11 to a rod J, forming a detent which can engage with the ratchet-wheel a This detent J may be formed of a tube jointed to the end 7 of the lever I. At the other end of the tube is mounted a fingerj, forming the detent proper, actuated by a spring 5', Fig. 5. At points kl of the disk H are attached two chains or cords K L, which are arranged along one of the shafts'and within reach of the driver.

To the crank of the shaft 12. is fastened a rod M, mounted at the other end on a pivot m, which forms the junction of two levers N O, of which one, N, is pivoted at a fixed point it and the other is jointed at 0 to a threearmed lever P p p. The lever O is of variable length. It is for this'purpose preferably formedof a tube 0, being guided on a hollow projection 19 solid with the lever P p p, and

IOO

lever P, these rods being connected totthe said disk 0 by the intermediation of the collar q. The crank-shaft h carries at its end on this side a pulley R, at a point r of which is fixed a cord or chain 'r, passing over a jockey-pulley r and attached to the head 8 of a rod S, guided in a slide 8 and in a tube 3 mounted on a pivot 8 Figs. 4, 10, and 11. The chain F carries a catch f, and the chain F carries a catch f. The catchf limits the travel of the chain F between two abutments f f and consequently limits the rotation of the cylinder a, carrying the springs. The catch f of the chain F is arranged to come into contact with the head 8 of the rod S.

The working of this is as follows: Forward starting, which is more often used, can be effected as well when the cart is in, the normal position as when it is turned over or tilted. In the normal working state the working parts are in the position represented by Figs. 1, 2, 3, and 4. When the driver wishes to stop by putting on the brake, he exerts a pull on the cord L, which makes the disk H turn in the direction 00. This by the rod G makes the lever cl pivot on the axis D, drawing the pinion e into gear with the toothed crown of the wheel B. This wheel then turns the pinion e and the toothed wheel 6, which is secured on the same shaft, and this latter draws the chain F, which thus puts in motion the pinion a and with it the cylinder, thus winding up the springs A. The duration of the motion necessary to the winding up of the springs A is determined by the travel of the catch f of the chain F between the stops f f While the rotation of the disk H has caused the pinion e to engage with the toothed crown b, the roller 7L2, engaged in the slide 71 of the lever 16, has turned this on the axis 2' and disengaged the catch from .the ratchet-wheel u When the winding of the springs is effected and the chain has made its complete travel, the catch f has come against f. The system is then locked and the wheel.

B of the cart skids. At this instant the driver exerts a pull on the cord K, (until the meeting in his hand of the cords K L,) which turns the disk H in the direction 11 and brings it back to its first position. This disengages the pinion e from the crown b and brings back the detent J into gear with the ratchet a The moving parts are then in the same state as before, except that the springs are wound up and form a reserve of energy representing the force given out in brakinga store which can be used at any moment. It is evident that the driver must exert the pull on the cord K when stopping his cart, for otherwise as soon as the horses had stopped the springs unwinding would pull the cart back. This action, moreover, is used in the case when it is desired to start backward. To make a forward start by using the force which has been stored up since the braking, the driver pulls down the cord K, thus turning the disk H in the direction y. The cranknew effort to release the cart.

shaft It being fastv to the disk H draws the rod M, which acts upon the jointed group of levers N and O. This brings the disk G into gear with the wheel B, and the teeth I) of the latter engage in the openings 0 of this disk, Figs. 2, 3, and 9. At the same time the disk H, working the lever I, has made the detent J release the ratchet a and the springs can then unwind, restoring the energy which they have accumulated. The pinions 0, and a draw the two chains F F. The chain F merely turns the wheel 6 and the pinion e, which latter is not in gear with the toothed hub b of the wheel B. The chain F draws the wheel B, since the latter is fast to the disk 0, and the cart is thus put into motion while the energy stored in the springs is being given out. When the springs have given out all their force, the disk 0 must be disengagedfrom the wheel B, for if these parts remained fast for even a short space of time-after the motive force was expended the apparatus would cause an injurious resistance and risk warping the springs, which would be turned the wrong way. In order to avoid this inconvenience, the automatic disengagement, Figs.

4, 10, 11, comes into play. At the end of the rotation determined by the springs A the catch f on the chain F (which at first was in the position shown in Fig. 4) comes into action against the head .9 of the rod S. This head 3 had been since the braking brought to the position 8 (shown dotted in Fig. 10) by the chain 7", attached to the pulley R, secured to the shaft h; By its displacement of s to s the head 3 draws the chain r and turns the disk R, which by means of the crank-shaft h, the rod'M, and the levers N and O disengages the disk Cfrom the wheel B. (See Fig. 2.) All the parts are then in the position in which they are seen in Figs. 1, 2, 3, and 4:, the springs being unwound. This mechanism can equally well be used to start the cart when it is tilted. The working is exactly the same. Moreover, shouldv the cart become stuck in mud or otherwise impeded and the energy of.

the springs has already been expended these can be wound up afresh, so as to obtain a For this purpose the horse or one of the horses may be unharnessed anl taken to the rear of the cart and harnessed to a chain or rope fastened to the catch f of the chain F. The latter is thus moved directly and the springs are wound up, the ratchet a being free to turn because of the yield of the spring of the detent J. When the chain has traveled so far that the catch f has come onto the chain-wheel c, it can be drawn no farther, and the springs are only half wound up. The drawing-chain is then hooked to one of the links of the chain F until the springs are completely wound up. Moreover, if there should not be sufficient room behind the drawing chain may be hooked to a point in the lower'portion of the chain F and-thewinding efifected from the front. The springs can thus be completely wound up without moving the cart, and this force can be used for starting.

I reserve the right to introduce into the mechanism of the storage brake just described all variations and modifications in construction compatible with the essential conditions laid down.

It is evident that the number of springs is variable according to the desired eifect in starting and stopping and that two or more boxes of springs can be placed parallel, connected by gear-wheels.

Such a storage-brake can be applied to all kinds of vehicles with animal or mechanical traction or to railway-carriages.

Having thus described my invention, what I claim as such, and desire to secure by Letters Patent, is-- l.
